Guindillas de Ibarra en Vinagre

Created by

Ibarra's slender green piparras, packed raw under cool white wine vinegar brine, stay mild, firm and gently tangy, exactly what a proper Donostia Gilda needs.

Guindillas de Ibarra en vinagre are Basque, from Ibarra in Gipuzkoa: young piparras preserved whole in white wine vinegar, water and salt until their bright green settles to olive and their grassy bite turns gently tangy. The thin skin, narrow body and mild heat make this a different pickle from a thick pepperoncino or a fierce green chilli. It is the backbone of a proper Gilda, not decoration on the skewer.

The method that decides the jar is simple. Dissolve the salt, cool the liquid completely, then add the vinegar and cover the raw peppers. Hot brine cooks their delicate walls and leaves them limp. Keep them under the liquid and give them time. Pésalo, no lo adivines, weigh it, don't guess, because the balance of vinegar, water and salt is what preserves their clean, mild character.

If Ibarra piparras don't grow where you are, use the youngest, narrowest mild green frying chillies you can find. Turkish sivri biber is the closest useful substitute, with shishito at a pinch. The first may carry more heat, while shishitos are shorter, wrinklier and less tidy on a Gilda. The jar cannot honestly bear Ibarra's name, but the method remains sound. No hace falta haber pisado España.

Give them two weeks before judging them, and three or four if you can wait. My margin beside this preserve says only, "brine cold, peppers under." Do those two things and it comes out. Siempre sale, si lo sigues.

Ibarra lies in Tolosaldea, Gipuzkoa, where the mild, humid Atlantic climate helped shape a long, thin pepper with tender skin and very little heat. Preserving the short summer crop in vinegar carried it through the rest of the year and made jars of piparras a fixture of the Basque pantry. In Donostia, the pickle joined a green olive and salted anchovy on the Gilda pintxo, named for the film character because the skewer was said to be green, salty and a little spicy.

The technique, the tradition, and the story behind every dish.

375ml

fine non-iodized sea salt

Quantity

15g

Equipment Needed

  • Two clean 750ml glass preserving jars with non-reactive lids
  • Digital kitchen scale
  • Measuring jug
  • Small stainless-steel or enamelled saucepan
  • Small glass pickle weights, optional

Instructions

  1. 1

    Clean jars and peppers

    Wash two 750ml preserving jars and their lids in hot soapy water, rinse well, then scald them with boiling water and leave them to drain. Rinse the piparras under cool water and dry them carefully. Discard any with splits, bruises or soft patches, then trim each stalk to about 1cm without cutting into the pepper.

    Choose young piparras with thin skins, narrow bodies and soft seeds. Once they grow thick and blunt, no brine can give them back their tenderness.
  2. 2

    Make the brine

    Put the water and salt in a small non-reactive saucepan. Warm gently, stirring, just until the salt dissolves. Remove from the heat and let the salted water cool completely, about 30 minutes, then stir in the white wine vinegar. The brine must be cool before it meets the peppers. Pour it hot and their thin walls soften instead of keeping that tender snap.

  3. 3

    Pack without bruising

    Pack the piparras into the cool jars, some upright and some curved around the sides, without crushing them. Leave about 2cm of space below each rim. Keep the peppers whole; pricking or splitting them lets the brine flood the hollow centres and makes them soften sooner.

  4. 4

    Cover and submerge

    Pour in the cool brine until every piparra is covered, leaving 1cm of headspace. Tap each jar gently against a folded cloth to release trapped air, then hold the peppers beneath the liquid with a small glass pickle weight if they float. Close the lids, label the jars with the date and refrigerate immediately.

    If you need more brine, mix equal measures of water and 5% acidity white wine vinegar, adding 20g salt for every litre of combined liquid. Don't top the jar up with plain water.
  5. 5

    Mature in the cold

    Leave the jars unopened in the refrigerator for at least 14 days. By then the bright green will have settled to olive, the raw grassy edge will be gone, and the vinegar will have reached the centre. They become rounder and more settled after three to four weeks. Take them out with a clean fork and keep the rest beneath the brine.

Chef Tips

  • Buy piparras while they are young, slender and green, usually from midsummer into early autumn. A good one bends without feeling hollow or leathery, and its seeds are still pale and soft.
  • No Ibarra piparras where you live? Use slender Turkish sivri biber if it is sold mild, or small shishito peppers at a pinch. Taste one from the batch first because either can hide a hot pepper among the mild ones.
  • Use white wine vinegar whose label states at least 5% acidity. Homemade vinegar with unknown acidity is for dressing food, not preserving it. A 6% vinegar is safe here but gives a sharper pickle.
  • This is a refrigerator pickle, not a shelf-stable canning recipe. Keep every jar refrigerated and every pepper beneath the brine. Discard the jar if you see mould, active bubbling, slime or an unpleasant smell.
  • For a Gilda, drain one or two piparras without rinsing them, fold them onto a skewer with a good salted anchovy and a green olive. No sugar, garlic or herbs belong in this jar; they cover the pepper instead of preserving its character.
  • The piparras keep for about three months refrigerated when handled with a clean fork. Their texture is best during the first eight weeks after maturation.

Advance Preparation

  • The brine can be mixed up to one day ahead and kept covered in the refrigerator. It must be completely cool before it is poured over the piparras.
  • Allow at least 14 days before serving. Three to four weeks gives a gentler vinegar bite and the settled olive-green colour expected from the preserve.
  • Keep the finished jars refrigerated from the moment they are filled. Open only with clean utensils and return them promptly to the cold.
